Flat rooflights in Oakham: what is involved?
Thinking about flat rooflights in Oakham? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
We cover all of Oakham and the LE15 district, and nearby Uppingham and Melton Mowbray.
What you can choose
- Plastered or lined internal reveal
- Insulated kerb or timber upstand built to suit
- Double or triple glazing
- Solar-control or self-cleaning outer pane
- Frame colours: anthracite, black, white or RAL
- Double or triple glazed with a warm-edge spacer
- Inner pane laminated for safety overhead
Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in Oakham
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about flat rooflights in Oakham
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
How do I book a survey in Oakham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Oakham?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
